Many circuit boards end up costing more than they should because of the money spent on design or as a result of poor design decisions. Some design groups have older work-flows that need updating or forced design decisions that no longer apply. Let’s look at the four main areas where you can reduce the expenses of printed circuit board development; fabrication, assembly, components, and the initial PCB design process.
With all of its activity, a circuit board can be a hostile environment for sensitive digital and analog signals. It is critical for the overall performance of the board to provide functional partitioning in the PCB design. Here are some ideas on how this can be done in your next circuit board layout.
Manufacturing a printed circuit board is a complicated process. From fabrication through assembly, there are many different points during manufacturing that must be verified before the board can pass to the next step. This validation can be done in several ways, from manual inspections to advanced X-ray analysis. Another standard validation method is the different automated optical inspection (AOI) systems used to examine PCBs.
Many variables can affect how much it will cost to have a raw circuit board fab built, and those prices can also change depending on which vendor you use. We’re going to look at some of these variables and how you can control PCB fabrication methods to reduce supply chain costs.
To help designers create functional and manufacturable circuit boards, the PCB design software creators will include a variety of design rules and constraints in their tools. The appearance and use of these constraints will vary quite a bit from tool to tool, but their purpose is always the same, to help you to design a better circuit board. Here are some ideas on how to set up and work with these rules.
Over the past several years, our confidence in the quality of the parts used has been violated by counterfeit parts’ proliferation on the market. The flood of counterfeits has required extra diligence in sourcing electronic components to ensure that what is purchased is the real McCoy and will work as expected when installed on a PCB. Here are some tips on how to ensure the components you are working with are genuine.
